General advice is to keep them separate, so they can’t see or even smell each other. I’d recommend washing your hands every time you touch them and go to the other one - I was bitten a couple times when I didn’t do that! Zelda absolutely HATED the smell of another female we kept on the other side of the house. We failed to bond these two unfortunately, they’d fight to death (bitten nose and chipped ears
) I really regret we didn’t know at the time there is a bonding specialist in the country...
Anyway, with Linky, younger sibling of Zelda, I ignored the advice to keep him in a different room cos she didn’t mind his smell at all. They only stayed at separate enclosures until Linky was well 6 weeks after getting fixed. The bonding was really tricky, but they are inseparable now.
The worst was waiting. First for the little fella to grow up to be fixed, then for his hormones to calm down. I had 3 unbonded bunnies at that time and I was going mental with changing 3 potties daily, maintaining cleanliness in 3 enclosures and making sure each of the buns gets their fair amount of time with me, all 3 separately
My life quality got much better after the siblings bonded and the third girl found her new dream home
So it’s worth the wait!!!
